2 things will make the trans dipstick keep blowing out...Either excess heat or an internal pressure leak that's pressurising the fluid in the pan.

Do you have a stall in it? Do you have a GOOD external transmission cooler? By GOOD, I mean a stack plate cooler, not a tube/fin cooler. B&M, TRU-COOL, and LONG sell stack plate coolers...Actually, the B&M , and TRU-COOL are made by LONG.

We did extensive research on transmission coolers at the shop a few years ago....With a temp guage going into and coming out of the coolers. The tube/fin type just aren't very efficient. A Grand National with an extremely high stall in it is what prompted us to test the different cooler types. With ANY tube/fin cooler we put on it, it would blow fluid out the vent. We ended up with a stack plate cooler that was physically smaller than the largest tube/fin cooler they make, and it solved the problem.

No, I do not have a big stall in it, it is stock. I checked it out last night and so far the stick has stayed in it since i pushed it back in like last week or so. I do have a tranny cooler on it but not sure which one it exactly is.

Thanks for the advice though

How do you guys get your dipstick in once it blows out without dropping the tranny?

 

Mine does it too -- the top of the dipstick (near where it comes out) looks like the air is getting to it. It's changing to somewhat of a red color.

 

I don't know of anyone with a 4L60E whose car DOESN'T do it...mine does it too.

 

Actually mine hasn't done it in over a week and a half. It was out like the week before last and i put it back down there and it has actually styed put Now that this is said, today it will come out
